To set a speed record in a measured (straight-line)
distanced, a race car must be driven first in one
direction (intime t1) and then in the opposite
direction (intime t2). (a) To
eliminate theeffects of the wind and obtain the car's
speedvc in a windless situation, what number
ofmethod should we use: the average
ofd/t1
andd/t2 (method 1) or should we
divided by the average of t1
andt2 (method 2)? (b) What is
thefractional difference in the two methods when a steady wind
blowsalong the car's route and the ratio of the wind
speedvw to the car's speed
vc is0.0540?
